also just so you know all ls3 and l99 engines come with an active fuel managment(dod) oil pressure relief valve built into the oil pan ( yes even the ls3 engines have this, probly cheaper for gm just to build all the oil pans with this valve) , and if you leave it in you will always be limited to 50psi max, as the valve opens at 50 psi and blows the oil right back into the oil pan.

a 1/4" pipe plug fits perfect if you remove the valve, i have had mine out since i built my engine 12,000 miles ago and it works perfect with the l99 pump,, the factory oil filters have their own oil pressure relief built into them.
